    When virtual scrolling is enabled, there is a problem with group footer aggregates. When i scroll table the aggregates (sum) are rendering only for visible data.

    gridOptions.dataSource.pageSize = 100;
    gridOptions.scrollable = {
        virtual: true


    Example in screenshots.

    Hello Daniel,

    Please note that grouping is not supported when virtual scrolling is enabled. If grouping is a requirement for your application I would recommend using paging instead of virtual scrolling for the Grid.

    If you would like more information on Virtual Scrolling and its limitations you would find the article below interesting.
